I get random messages but when I tried to follow the main websites instructions for latest wine I get

sudo apt install --install-recommends winehq-stable

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
winehq-stable:i386 : Depends: wine-stable:i386 (= 4.0~bionic)
E: Unable to correct problems, you have held broken packages.

Been having the same challenge on the RockPro64...
I installed a Debian Buster image...

Anyway, what I've been able to figure out is that the issue is that FAudio is a dependency and it's this standing in the way.
Found that out by apt-get installing each package listed as a missing dependency, down the chain, until I got stuck at libfaudio0 which is not in any repo (source) that I can find so far (i.e. as per the message above, you'd apt-get install wine-stable:i386, which would then list the next dependency, and so on).

So, there isn't a compatible build for FAudio it seems..
I have subsequently read that building wine yourself *could* work; as in, the dependencies don't all have to be met if building from source (some things may not work as expected then of course).
This is a next step I need to take after getting back to a cleaner version of my OS install after all my tweaking...
